Assessment of gamma dose-rate heterogeneity in the fanglomerate environment was carried out by splitting the fanglomerate samples into 2 mm and 2 mm size fractions, and comparing data from high-resolution gamma spectrometry and ICP -AES/-MS analyses of the size fractions.The two fanglomerate sample evaluation demonstrates that single grain analysis and finite mixture modeling (FMM) are essential for De assessment.The additional part of this book deals with the dynamics, rare-earth ions, photon down-/up-converting materials, luminescence dating, lifetime, bioluminescence microscopical perspectives and prospects towards the basic research or for more advanced applications.

Regarding this new approach, issues of partial bleaching and gamma dose-rate heterogeneity should be carefully considered; yet this is worthwhile since this method can greatly expand the applicability of OSL dating in similar settings.

In tectonically active arid and semi-arid regions like southern California, alluvial fans and their drainages record not only paleoenvironmental change but also fault movement.

To be able to decipher this precious information, a suitable chronological method is required.

The paleosol layer (78.81 ± 8.04 ka) beneath this fluvial setting suggest that soil development occurred mainly during the interglacial period MIS 5.

In the Indio Hills (north of Biskra Palms) site, almost all depositional ages lie within interglacial periods: MIS 3, MIS 5, MIS 9 and the Holocene.
